smooth wombat (796938) writes "Thirty years ago, a signal was received by Ohio State University's Big Ear Radio Observatory which, for a brief moment, set the scientific community ablaze. Had we heard the first proof of an intelligent civilization outside our own?
Unfortunately, the signal was not repeated and has not been heard from since despite the best efforts of astronomers during the last three decades. The debate over what the signal actually was continues to this day but new help is on the way. The SETI institute will soon be using the Allen Telescope Array in California to search the same area of sky. The array uses dozens of separate radio dishes to produce an instrument that will eventually become more sensitive than the world's largest single-dish telescope in Aricebo."
